sHUTTER-SLAT FASTENER.

SPECIFICATION formingpart of Letters Patent No. 663,556, dated December11, 1900.

Application filed January 17, 1900. Serial No. 1,718. (No model.)

To all whom, it may 00u/cern,.-

Be it known that I, WILLIAM L. AMBLER, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented a certain new and useful Improvement'in SlatFasteners or Retainers for /Vindow Shutters or Blinds, of which thefollowing is a specifica tion.

My invention relates to a new and useful improvement in slat fastenersor retainers for window shutters or blinds, and has for its object toprovide a simple and effective device which may be attached to a shutteror blind and to the connecting-rod of the slats, and thereby the saidslats may be adjusted at any angle or closed or opened by simplymanipulating the fastener, and when so adjusted the fastener will firmlyhold the slats in their adjnstments.

Vith these ends in view this invention consists in the details ofconstruction and coinbination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation willnow be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure l is an elevation of a portion of a shutter or blind, showing myimprovement attached thereto and to the connecting-rod of the slats, thelatter being closed; and Fig. 2, an end view ofa portion of the slatsand connecting-rod, the end rail of th'e shutterbeing sectioned away, soas to clearly show the connection between the fastener and theconnecting-rod. Fig. 3 is a fragmental View showing the inner surface ofone of the ears.

In carrying out my invention as here embodied, A represents the shutteror blind, B the slats pivoted therein, so as to turn horizontally, and Cthe connecting-rod pivoted to each of the slats, so as to operate thesame in unison, all of which is well known.

A bracket D is secured to the bottom rail of the shutter or blind bymeans of the screws E or in any other convenient manner, and from thisproject the ears F, between which runs the pivot-wire G. Upon thispivot-wire is secured the short arms H, and the sliding blocks I are sofitted to these arms as to freely move longitudinally thereon for thepurpose hereinafter set forth. The upper end of the blocks I are pivotedat J to the clip K, which latter is secured to the connecting-rod C bymeans of the screws L or in any other suitable manner. l By thisarrangement it will be seen that the swinging of the arms H will swingthe blocks in such manner that the connecting-rods C will be caused tomove the slats by reason of the blocks sliding upon the arms, as beforeset forth. For convenience in bringing about this movement I provide twooperating-levers M, which are also pivoted upon the wire G, and I preferthat these levers should be made of spring metal, so as to be deflectedinward, for the purpose hereinafter set forth, and they pass upwardthrough slots N, formed in the blocks I, so that said blocks may slideupon these arms, while the latter shall have suicient sidewise play tobe sprung inward, as before set forth. The upper'end's of the levers Mterminate in finger-pieces O, by means of which the levers may bereadily sprung inward by being grasped between the thumb and foreingerand may thereafter be swung upon the wire G, so as to bring about themovement of the blocks I, and consequently the operation of theconnecting-rod C, as before stated.

The object of the levers being of spring material is that they may serveto lock the fastener in any adjustment, and this is accomplished by thepoints N, projecting from the lower portion of each of the levers andsecured thereto in any convenient manner, so

as to enter into engagement with theA inner walls of the ears F, whichwalls may be notched or roughcned, if found necessary, and thus serve toengage and hold the points when sprung outward, which in turn will holdthe fastener in its adjustment.

In practice when the adjustment of the slats is to be changed this isreadily accomplished by grasping the upper ends of the operatinglevers,springing them inward until the points are disengaged from the innerwalls of the ears, and then swinging these levers to the desiredposition and again releasing them, which will effect the locking thereofin their last adjustment, as before mentioned.

IOO

The use of my improved fastener proves to be of great advantage, sinceunder ordinary circumstances it is difficult to adjust the slats of ashutter or blind and have them remain in thaty adjustment against astrong draft; but, as is obvious, this is readily and eectuallyaccomplished by the use of my improve ment.

The cost of manufacture of my improved fastener is comparatively smalland is readily attached by a person of little or no skill.

Having thus fully described my invention, what I claim as new and usefulis- 1. In combination with a shutter or blind, a Slat-fastenerconsisting of a suitable bracket adapted to be secured to the bottomrail, arms pivoted to said bracket, sliding blocks fitted upon saidarms, a clip secu red to the connecting-rod of the slats and having saidblocks pivoted thereto, two operating-levers also pivoted to thebracket, and points carried by said levers adapted to engage with theears of the bracket, as and for the purpose set forth.

2. The herein-described combination of a bracket adapted to be securedto the bottom rail of the sh utteror blind, ears having roughened innersurfaces formed with said bracket, arms pivoted between the ears, blocksfitted to slide upon said arms, a clip to which these blocks arepivoted, said clips being secured to the connecting-rod of the slats,two operating-levers also pivoted between the ears, and points carriedby levers adapted to engage with the roughened surfaces of the ears, asspecified.

3. A Slat-fastener consisting of a bracket having ears formed therewith,a pivot-wire secured within. said ears, two arms pivoted upon said wire,two blocks fitted to slide upon the arms, said blocks being pivotallyconnected with the slatrrod having grooves formed in the sides thereof,two exible levers also pivoted ulpon the pivot-wire, said levers passingthrough the grooves formed in the blocks, a finger-piece formed` u-ponthe outer end of each of the levers whereby they may be manipulated, andpoints carried by each of the levers for engagement with the innerwallsof the ears in holding the fastener in adjustment, as shown andspecified.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

WILLIAM L. AMBLER.
